RAR archive of about 262 KB for the Z97-K motherboard, with the revision marked as R2.0 in the file name. The name does not describe what is packed inside, so unpack it to see whether it holds a boardview, a schematic or both. Files like these are used to trace power rails, locate components and pick probe points while diagnosing shorts or missing voltages. Boardviews open in tools such as OpenBoardView. Since another Z97-K archive without a revision tag also exists, check that your PCB is marked 2.0 before using this set.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @boardview. Enginerys does not host this file.
